Comet and Blizzard marry. On their wedding night, Comet finds a bracelet, just one, mind you, with a note that says "in case you feel like getting kinky. I'm 65% sure it's not the one your parents use." Comet responds by going to Fluttershy's house and angrily pelting Discord with rocks, which just makes him laugh and makes Fluttershy exasperated.

Comet and Blizzard have a daughter. Comet and Blizzard both get into the medical field regarding their cutie marks, with Comet eventually getting her doctorate. TD finds the phrase Dr. Comet endlessly amusing, but is naturally proud of her.

The three of them stay in Ponyville, and as TD's granddaughter grows up, she loves playing with her grandfather, and the two become very close. However, time marches on, and TD gets older and older. He goes completely gray, he needs glasses, but he keeps fit. Comet's daughter has a pair of twins of her own.

Eventually time catches up to him, and he has a heart attack that he doesn't fully recover from. A few years later, he's on his death bed. He's visited by Celestia one last time, and he lightly punches her in the face for old time's sake. Shortly after he passes peacefully and without regret, surrounded by his loving family.

I do wish that I could have finished it for all of you, but life didn't work out that way. I did want to give closure on it, though, so I hope you like that.

Thank you for all these years of reading TD.
